Efektifitas Biopriming Pada Benih Cabai (Capsicum annuum L.) Kedaluwarsa Menggunakan Rizobakteri
Abstract
Expired seeds generally experience a decline in viability and vigor due to deterioration, which leads to poor growth and yield when used in cultivation. One effort to restore the quality of expired seeds is through biopriming using rhizobacteria. This study aimed to determine the effectiveness of biopriming on expired chili (Capsicum annuum L.) seeds. The research was conducted at the Seed Science Laboratory, Department of Agrotechnology, Faculty of Agriculture, Darussalam Banda Aceh, from November 2024 to January 2025. A Completely Randomized Design with a non-factorial pattern was used, consisting of five rhizobacterial treatments: control (without rhizobacteria), AT 7/1 T, KI 8/4, PS 4/2, and PS 5/6, each replicated three times. Observed parameters included maximum germination potential, germination rate, vigor index, germination uniformity, germination speed, time to reach 50% total germination, plant height (at 15, and 30 DAS), number of leaves, fresh weight, and dry weight. The results showed that biopriming with rhizobacteria had a highly significant effect on maximum germination potential, germination rate, germination speed, time to reach 50% total germination, and dry weight; a significant effect on vigor index, germination uniformity, fresh weight, and seedling height at 15 and 30 DAS; but no significant effect on the number of leaves at all observation ages. The best treatment was obtained with PS 4/2 rhizobacteria, which optimally improved the viability and vigor of expired chili seeds.
